//                             This is a custom fork of [[User:DemonDays64/Scripts/Dumb quotes.js]]

// NOTE: Uses a regex feature implemented fairly recently in some browsers (https://caniuse.com/?search=Lookbehind):
// Chrome: 10/2017 | Firefx: 6/2020 | Edge: 1/2020 | Safari: 3/2023 | Opera: 11/2017
// If running older browsers I believe it will work normally except that it will modify File links. The previous versions did not have this feature and used widely-supported Regex.
